"I would say that people are at their most creative when under constraints," Bolten ventures with a shrug. "It's only when people have to find ways around a problem that true innovation happens. When I was designing that drill for the sewers project, my first thought was for it to have just a single giant drill bit made of adamantine. Given the shortages of adamantine at the time, that would have simply costed too much to be viable. I had to get creative to do the same job while minimizing the amount of adamantine in the design."
